In relation to the remarkable effect of emulsified diesel oil with water particles on reducing exhaust pollutants (NOx, soot etc.) and also specific fuel consumption of the diesel engines, the micro-explosion phenomena in the flame of a heated fuel droplet on a silica filament in a high pressure chamber investigated experimentally. The experimental results are summarized as follows: With the increase of the initial air pressure in the chamber, (1) The micro-explosion likely becomes weaker, so that the projected flame area on the motion picture of 8-mm wide gets smaller. (2) The difference between the flame shape of the emulsion and that of diesel oil gets less. (3) The burning time of an emulsified fuel droplet increases approaching that of diesel oil droplet. As a result, the authors appraise the effect of the micro-explosion on reducing specific fuel consumption and exhaust smoke of a diesel engine to be small because of the high pressure in the engine cylinder.
